Call it the Ultra-Ultra Deep Field. The Hubble Space Telescope has used its new Wide Field Camera 3 to take the deepest near-infrared image of the universe ever made, revealing galaxies as they were about 600 million years after the big bang. The image was taken in the same region of sky as Hubble's "Ultra Deep Field", which in 2004 became the deepest visible-light image, showing galaxies 700 million years after the big bang.

Wide Field Camera 3 is two to three times as sensitive as the near-infrared camera used to take previous Hubble deep-field images, NICMOS. (Image: NASA/ESA/G. Illingworth/UCO/Lick Observatory/UCSC/R. Bouwens/Leiden University/HUDF09 Team)
